BLAST is a computer algorithm uas muaj rau siv online ntawm National Center for Biotechnology Information (NCBI) lub vev xaib, nrog rau ntau qhov chaw. BLAST tuaj yeem hloov kho sai thiab sib piv cov lus nug DNA ib ntus nrog cov ntaub ntawv ntawm cov kab ke, uas ua rau nws yog ib qho tseem ceeb hauv kev tshawb fawb genomic tsis tu ncua.
Puas BLAST yog thawj qhov chaw khaws ntaub ntawv?
BLAST yog software siv dav tshaj plaws hauv kev tshawb fawb bioinformatics. Nws lub luag haujlwm tseem ceeb yog los sib piv cov kev txaus siab ib ntus, cov lus nug ib ntus, ua ntu zus hauvloj database BLAST tom qab ntawv tshaj tawm qhov kev sib tw zoo tshaj plaws, lossis " hits," pom hauv cov ntaub ntawv. Qhov kev pab cuam yooj yim no muaj ob daim ntawv thov thawj.
Is NCBI is a database?
Lub NCBI lub tsev a series ntawm databases cuam tshuam rau biotechnology thiab biomedicinethiab yog ib qho chaw tseem ceeb rau bioinformatics cov cuab yeej thiab cov kev pabcuam. Cov ntaub ntawv tseem ceeb suav nrog GenBank rau DNA ib ntus thiab PubMed, cov ntaub ntawv sau cia rau biomedical cov ntaub ntawv. Lwm cov ntaub ntawv suav nrog NCBI Epigenomics database.
Puas yog BLAST tsuas yog ua haujlwm hauv NCBI databases?
BLAST muaj nyob rau hauv lub vev xaib ntawm NCBI lub vev xaib. Ntau hom BLASTs muaj raws li cov lus nug ua ntu zus thiab cov phiaj xwm databases.
BLAST database ua haujlwm li cas?
BLAST ua haujlwm li cas? BLAST txheeb xyuas homologous sequences siv txoj kev heuristic uas pib pom qhov sib tw luv ntawm ob ntu; yog li, txoj kev tsis siv tag nrho qhov chaw sib lawv liag mus rau hauv tus account. Tom qab thawj qhov kev sib tw, BLAST sim pib cov kev sib tw hauv zos los ntawm cov kev sib tw thawj zaug.
